Thousands of gold is the highest purity (usually marked with 999, 9999). Platinum is marked with Pt, but PD is palladium, which is cheaper than platinum, such as pt950. The PT in the front indicates that it is made of platinum, and the 950 in the back represents the purity of gold. Now platinum is 990, which improves the purity. 2. More details below! As early as 6000 years ago, mankind knew that there was gold and used it as decorations. The gold jewelry popular in the international and domestic markets today mainly includes pure gold, K-gold, gold plating, gold wrapping, imitation gold and discolored gold. Pure gold jewelry is made of pure gold. As the saying goes, "there is no shortage of gold", that is to say, the content of pure gold is less than 100%. In fact, those with a gold content of 99% and 99.9% are called pure gold products. This pure gold jewelry is soft in texture, red and yellow in color, and will never fade. However, it is easy to deform and wear, and cannot be inlaid with various exquisite gems. K gold is to add a small amount of silver, copper, zinc and other metals to gold to enhance the strength and toughness of gold. In order to express the gold content in K gold, K value is commonly used. The gold content of 1K is about 4.166%. The gold content of 24K is about 99.99%, so it is pure gold. The materials used as gold jewelry are generally 22K (gold content is about 91.65%), 20K (gold content is about 83.32%), 18K (gold content is about 74.98%) and 14k (gold content is about 58.2%). The style of K-gold jewelry is easy to renovate. It can be inlaid with various kinds of diamonds, emeralds, pearls, gems and carved saws to create various exquisite patterns.

Gold plated jewelry is a layer of 24K gold plated on the surface of jewelry made of copper, silver or alloy. Its appearance is the same as that of pure gold jewelry. However, the plated metal is not durable and will be worn after a long time. Gold coated jewelry is made by wrapping gold foil on the surface of jewelry made of aluminum, zinc and lead alloy, then heating and pressing the gold foil firmly on the product with tools. The quality of gold-clad jewelry is harder than that of pure gold jewelry. It is not easy to deform and has strong wear resistance. On the surface, it can be comparable to 24 karat gold jewelry. Imitation gold jewelry is a kind of jewelry similar to K gold made by special plating process. This kind of jewelry is made of copper, zinc, aluminum and other metals as raw materials, and then put into a special plating solution. After treatment, the surface is plated with a layer of red yellow bright coating like gold. Although this kind of jewelry does not contain any gold, it looks like pure gold. At present, there are many exquisite imitation gold jewelry at home and abroad to replace pure gold jewelry. Chameleon gold jewelry is a new kind of jewelry made of K gold material after special processing. If diamond atoms are implanted on the surface of K-gold, a beautiful blue color will appear; A very fine metal particle can be electroplated on the surface of K-gold to show black. Japan has also developed dazzling purple alloy jewelry with gold content of 78% and aluminum content of 22%. Now, red, yellow, white, purple and other colors have entered the kkin family. At present, this magical and changeable color changing gold shoupei has been popular at home and abroad, and it is popular among the youth three. The method of identifying the true and false gold is: 1.
